Have any of you heard of the practice of draining a chiller this part of the glycol loop? I understand shutting it down for the season but I do not understand why you would go through the trouble of draining it? In all my time in the trade I've never been asked to do this, I have a few chillers did I winterize by draining the water from them and running glycol through them but I've never heard of this. Thanks in advance for your responses?
